Help with understanding chaining in Javascript

[azegurb]

hi All,
I have question around Douglas Crockford "method" method.

Function.prototype.method = function (name, func) {
    this.prototype[name] = func;
    return this;
};
function azerizor(value) {
this.value=value;
}


azerizor.method('toString', function () {

    return this.value;
});
var me = new azerizor('salam').toString();

alert(me); 

this is it. But here arises question regarding return this?
what does mean here return this? this method works without return this. I have read about that. so that one say that it is for chaining. But i didnt understand how can i use chaining using this "method" function. Thanks in advance for attention. I will wait your responses!

The chaining mechanism is handy if you want to add more than just one prototype to the function you're extending, for example:

Function.prototype.method = function(name, func)
{
	this.prototype[name] = func;
	return this;
};
function azerizor(value)
{
	this.value = value;
}


azerizor
	.method('toString',     function() {return this.value;})
	.method('toStringMore', function() {return this.value + ' more';})
	.method('bothFuncs',    function() {return this.toString() + ' ' + this.toStringMore();});

var me = new azerizor('salam');

alert(me.toString());
alert(me.toStringMore());
alert(me.bothFuncs());

If "return this" was not included then the second and third calls to the "method" function would not have worked.
Just note that there is no semi-colon until right at the end of the chain.
